Not sure if this is a bug with new version Huh

The GPU are not ordered when displaying HashRate.

You can see GPU1 is showing first ??

ZM uses CUDA_DEVICE_ORDER. Nvidia specifies it's default behaviour like this:
FASTEST_FIRST causes CUDA to guess which device is fastest using a simple heuristic, and make that device 0, leaving the order of the rest of the devices unspecified.

The default behaviour can be changed by setting the environment variable 'CUDA_DEVICE_ORDER' to 'PCI_BUS_ID' which causes CUDA to order the devices by '... PCI bus ID in ascending order'.

The documentation for this is located at: http://docs.nvidia.com/cuda/cuda-c-programming-guide/index.html#env-vars

... this is from a couple threads before...
